The hero Conall Carnagh, sitting in his dun afar off, heard the moan of the shield and the roar of the Wave of Tuath: and springing up from where he sat, he said: "Verily, the king is in danger: I will go to his rescue."
He ran with the swiftness of the wind, and arrived on the Green of Emain, where the two young heroes were fighting. Thinking it was Concobar that crouched beneath the shield, he attacked Illan, not knowing him, and wounded him even unto death. And Illan looking up said, "Is it thou, Conall? Alas, dreadful is the deed thou hast done, not knowing me, and not knowing that I am fighting in defence of the sons of Usna, who are now in deadly peril from the treachery of Concobar."
And Conall, finding he had unwittingly wounded his dear young friend Illan, turned in his grief and rage on the other, and swept off his head. And he stalked fierce and silent out of the battlefield.
Illan, still faithful to his charge, called aloud to Naisi to defend himself bravely: then putting forth his remaining strength, he flung his arms, namely, his sword and his spears and his shield, into the Red Branch; and falling prone on the green sward, the shades of death dimmed his eyes, and his life departed.
And now when it was the dusk of evening, another great battalion of the hirelings assailed the Red Branch, and kindled fagots around it: whereupon Ardan sallied out with his valorous band and scattered them, and put out the fires, and held guard for the first third of the night. And during the second third Ainnli kept them at bay.
Then Naisi took his turn, issuing forth, and fought with them till the morning's dawn: and until the sands of the seashore, or the leaves of the forest, or the dew-drops on the grass, or the stars of heaven are counted, it will not be possible to number the hirelings that were slain in that fight by Naisi and his band of heroes.
And as he was returning breathless from the rout, all grimy and terrible with blood and sweat, he spied Lavarcam, as she stood watching the battle anxiously; and he said:—"Go, Lavarcam, go and stand on the outer rampart, and cast thine eyes eastwards, if perchance thou shouldst see Fergus and his men coming."
For many of Naisi's brave followers had fallen in these encounters: and he doubted that he and the others could sustain much longer the continual assaults of superior numbers. And Lavarcam went, but returned downcast, saying she saw nought eastwards, but the open plain with the peaceful herds browsing over it.
